Description

[001] A presente invenção refere-se a novos compostos e métodos para a produção de inibidores de enzimas desubiquitilantes (DUBs). Em particular, a invenção refere-se à inibição de Cezanne 1. A invenção refere-se ainda ao uso de inibidores de DUB no tratamento de câncer.[001] The present invention relates to new compounds and methods for the production of de-ubiquitylating enzyme inhibitors (DUBs). In particular, the invention relates to the inhibition of Cezanne 1. The invention further relates to the use of DUB inhibitors in the treatment of cancer.

Antecedentes da InvençãoBackground of the Invention

[002] A listagem ou discussão de um documento do estado da técnica aparentemente publicado neste relatório descritivo não deve ser necessariamente considerada reconhecimento de que o documento faz parte do estado da técnica ou é de conhecimento geral comum.[002] The listing or discussion of a prior art document apparently published in this specification should not necessarily be considered recognition that the document is part of the prior art or is common general knowledge.

[003] Ubiquitina é uma proteína pequena que consiste em 76 aminoácidos e que é importante para regulação da função proteica na célula. A ubiquitilação e a desubiquitinação são processos mediados por enzimas por meio dos quais a ubiquitina é covalentemente ligada ou clivada de uma proteína-alvo. Estes processos já foram implicados na regulação de muitas funções celulares que incluem progressão do ciclo celular, apoptose, modificação de receptores da superfície celular, regulação da transcrição de DNA e reparo de DNA. Por conseguinte, o sistema da ubiquitina já foi implicado na patogênese de numerosos estados de doença que incluem inflamação, infecção viral, disfunção metabólica, distúrbios do SNC, e oncogênese.[003] Ubiquitin is a small protein consisting of 76 amino acids and which is important for regulating protein function in the cell. Ubiquitylation and deubiquitination are enzyme-mediated processes through which ubiquitin is covalently attached to or cleaved from a target protein. These processes have been implicated in the regulation of many cellular functions that include cell cycle progression, apoptosis, modification of cell surface receptors, regulation of DNA transcription, and DNA repair. Therefore, the ubiquitin system has been implicated in the pathogenesis of numerous disease states that include inflammation, viral infection, metabolic dysfunction, CNS disorders, and oncogenesis.

[004] As moléculas de ubiquitina são clivadas das proteínas enzimas desubiquitilantes (DUBs), sendo que existem aproximadamente 95 DUBs nas células humanas, divididas em subfamílias com base na homologia das sequências. A família dos tumores de ovário (OTU) consiste em pelo menos 14 DUBs ativas e caracteriza-se pela presença de um domínio de OTU e pela tendência a clivar cadeias de ubiquitina de forma específica para a ligação. Cezanne 1, também conhecida como OTUD7B, é uma proteína de 843 aminoácidos que foi identificada devido a sua semelhança com o membro A20 da família de OTU que mostrou bioquimicamente ter uma forte preferência por ligações da cadeia de ubiquitina K11.[004] Ubiquitin molecules are cleaved from de-ubiquitylating enzyme proteins (DUBs), and there are approximately 95 DUBs in human cells, divided into subfamilies based on sequence homology. The ovarian tumor (OTU) family consists of at least 14 active DUBs and is characterized by the presence of an OTU domain and the tendency to cleave ubiquitin chains in a binding-specific manner. Cezanne 1, also known as OTUD7B, is an 843 amino acid protein that was identified due to its similarity to member A20 of the OTU family that has been biochemically shown to have a strong preference for K11 ubiquitin chain linkages.

[005] Foi demonstrado que a Cezanne 1 age como um regulador negativo tanto da via canônica quanto da não canônica de NF-KB. Foi demonstrado que a Cezanne 1 age na via canônica processando cadeias K63 na proteína RIP1 e na via não canônica por desubiquitilação do componente inibitório TRAF3 (fator 3 associado ao receptor de TNF). Também foi demonstrado que ela desempenha um papel na hipoxia regulando os níveis da proteína HIF1a (fator 1a induzível por hipoxia). O siRNA da Cezanne 1 diminuiu os níveis da proteína HIF1a quando em hipoxia e, por conseguinte, diminuiu a expressão do gene alvo de HIF1a. O nocaute da Cezanne 1 levou a níveis mais altos de apoptose subsequente à hipoxia. Como o HIF1a possui propriedades oncogênicas, e a Cezanne 1 tem um papel pro- sobrevivência na hipoxia, foi sugerido que a Cezanne 1 seria um alvo satisfatório para intervenção farmacológica.[005] It has been demonstrated that Cezanne 1 acts as a negative regulator of both the canonical and non-canonical NF-KB pathways. It has been demonstrated that Cezanne 1 acts in the canonical pathway by processing K63 chains in the RIP1 protein and in the non-canonical pathway by dysubiquitylation of the inhibitory component TRAF3 (TNF receptor-associated factor 3). It has also been shown to play a role in hypoxia by regulating the levels of the protein HIF1a (hypoxia-inducible factor 1a). Cezanne 1 siRNA decreased HIF1a protein levels when in hypoxia and, therefore, decreased HIF1a target gene expression. Cezanne 1 knockout led to higher levels of apoptosis subsequent to hypoxia. As HIF1a has oncogenic properties, and Cezanne 1 has a pro-survival role in hypoxia, it has been suggested that Cezanne 1 would be a satisfactory target for pharmacological intervention.

[006] Foi mostrado que a Cezanne 1 facilita a ativação de células T e respostas inflamatórias regulando a ubiquitinação de ZAP70 (Hu et al. 2016 Journal of Exploratory Medicine). Isto mostra que a inibição da Cezanne 1 levaria a uma redução na resposta inflamatória. Há uma constante necessidade de compostos que inibam DUBs tais como a Cezanne para o tratamento de inflamação.[006] Cezanne 1 has been shown to facilitate T cell activation and inflammatory responses by regulating ZAP70 ubiquitination (Hu et al. 2016 Journal of Exploratory Medicine). This shows that inhibition of Cezanne 1 would lead to a reduction in the inflammatory response. There is a constant need for compounds that inhibit DUBs such as Cezanne for the treatment of inflammation.

[007] Foi demonstrado que a Cezanne 1 desempenha um papel na proliferação, migração e invasão celulares antagonizando a internalização e degradação do EGFR (receptor do fator de crescimento epidérmico). A Cezanne 1 e a Cezanne 2 foram identificadas em uma triagem genética em busca de uma enzima DUB para EGFR. A superexpressão da Cezanne 1 levou a níveis mais altos de EGFR fosforilado, níveis mais baixos de EGFR ubiquitilado e estabilização do EGFR. Em células de câncer de mama MDA-MB-231, o nocaute da Cezanne 1 levou à invasão e migração reduzidas. Análise do Atlas do Genoma do Câncer de Pareja et al. (2012) mostrou que a Cezanne 1 era superexpressa no câncer de mama e amplificação do gene foi observado em um terço dos tumores de mama. O nível de expressão da Cezanne 1 está correlacionado com um prognóstico pobre. Embora exista um punhado de inibidores de DUB publicados na literatura, há uma necessidade constante de compostos e composições farmacêuticas que inibam as DUBs tais como Cezanne 1 e USP30 para tratamento de câncer ou outras indicações nas quais a atividade da DUB seja observada.[007] Cezanne 1 has been shown to play a role in cell proliferation, migration and invasion by antagonizing the internalization and degradation of EGFR (epidermal growth factor receptor). Cezanne 1 and Cezanne 2 were identified in a genetic screen looking for a DUB enzyme for EGFR. Overexpression of Cezanne 1 led to higher levels of phosphorylated EGFR, lower levels of ubiquitylated EGFR, and stabilization of EGFR. In MDA-MB-231 breast cancer cells, knockdown of Cezanne 1 led to reduced invasion and migration. Analysis of the Cancer Genome Atlas by Pareja et al. (2012) showed that Cezanne 1 was overexpressed in breast cancer and amplification of the gene was observed in one third of breast tumors. The level of Cezanne 1 expression correlates with a poor prognosis. Although there are a handful of DUB inhibitors published in the literature, there is a constant need for compounds and pharmaceutical compositions that inhibit DUBs such as Cezanne 1 and USP30 for cancer treatment or other indications in which DUB activity is observed.

Therefore, the alkoxy may be linked to the rest of the molecule through a carbon, for example, -CH2CH2OCH3, or alternatively, the alkoxy is linked to the rest of the molecule through an oxygen, for example, -OC1-6 alkyl. In one example, the alkoxy is bonded to the rest of the molecule through an oxygen, but the alkoxy group contains an additional oxygen atom, for example, -OCH2CH2OCH3.

The nitrogen and sulfur atoms of the heteroaryl ring are optionally oxidized, and the nitrogen atoms are optionally quaternized. A heteroaryl ring may be a single aromatic ring or a fused bicyclic ring where the bicyclic ring system may be aromatic, or one of the fused rings is aromatic and the other is at least partially saturated. In one example, a bicyclic heteroaryl is one that the entire fused ring system is aromatic. A bicyclic heteroaryl may have at least one heteroatom in any of the fused rings. For example, a bicyclic ring with an aromatic ring fused to a partially saturated ring may contain at least one heteroatom in the aromatic ring or the partially saturated ring. The attachment of the bicyclic ring to the group in which it is a substituent can be via a heteroatom-containing ring or a carbon-only ring. The point of attachment of the heteroaryl to the group in which it is a substituent can be via a carbon atom or a heteroatom (e.g. nitrogen). In cases where ring A is a heteroaryl, the ring is an aromatic ring and may be fused to another aromatic or partially saturated ring.

[0039] Métodos gerais para a produção de sais são bastante conhecidos pelo especialista na técnica. Estes sais podem ser formados por meios convencionais, por exemplo, por reação de uma forma de ácido livre ou de base livre de um composto com um ou mais equivalentes de um ácido ou base apropriada, opcionalmente em um solvente, ou em um meio no qual o sal seja insolúvel, seguido por remoção do referido solvente, ou do referido meio, por meio de técnicas tradicionais (por exemplo, a vácuo, por secagem por congelamento ou por filtração). Os sais também podem ser preparados por troca de um contraíon de um composto na forma de um sal por um outro contraíon, por exemplo, usando uma resina de troca iônica adequada.[0039] General methods for producing salts are well known to those skilled in the art. These salts may be formed by conventional means, for example, by reacting a free acid or free base form of a compound with one or more equivalents of an appropriate acid or base, optionally in a solvent, or in a medium in which the salt is insoluble, followed by removal of said solvent, or said medium, by means of traditional techniques (e.g., vacuum, freeze-drying or filtration). Salts can also be prepared by exchanging a counterion of a compound in the form of a salt for another counterion, for example using a suitable ion exchange resin.

[0040] Quando os compostos da invenção existem em diferentes formas enantioméricas e/ou diastereoisoméricas, a invenção refere-se a esses compostos preparados como misturas isoméricas ou racematos presentes seja em uma forma oticamente pura ou como misturas com outros isômeros. Os enantiômeros diferem entre si apenas por sua capacidade de girar a luz plano-polarizada em quantidades iguais em direções opostas e são designados pelas formas (+)/(S) ou (-)/(R), respectivamente. Os enantiômeros ou isômeros individuais podem ser preparados por métodos conhecidos na literatura, tais como resolução ótica de produtos ou intermediários (por exemplo, separação por cromatografia quiral, por exemplo, HPLC quiral, ou uma abordagem de síntese assimétrica). Similarmente, quando os compostos da invenção existem como formas tautoméricas alternativas, por exemplo, ceto/enol, amida/ácido imídico, a invenção refere-se aos tautômeros individuais isolados, e a misturas dos tautômeros em todas as proporções.[0040] When the compounds of the invention exist in different enantiomeric and/or diastereoisomeric forms, the invention refers to these compounds prepared as isomeric mixtures or racemates present either in an optically pure form or as mixtures with other isomers. The enantiomers differ from each other only in their ability to rotate plane-polarized light by equal amounts in opposite directions and are designated by the forms (+)/(S) or (-)/(R), respectively. Individual enantiomers or isomers can be prepared by methods known in the literature, such as optical resolution of products or intermediates (e.g., separation by chiral chromatography, e.g., chiral HPLC, or an asymmetric synthesis approach). Similarly, when the compounds of the invention exist as alternative tautomeric forms, for example, keto/enol, amide/imidic acid, the invention relates to isolated individual tautomers, and to mixtures of the tautomers in all proportions.

IsótoposIsotopes

[0041] Os compostos descritos neste pedido podem conter uma ou mais substituições isotópicas, e uma referência a um elemento particular inclui em seu escopo todos os isótopos do elemento. Por exemplo, uma referência a hidrogênio inclui em seu escopo 1H, 2H (D), e 3H (T). Similarmente, referências a carbono e oxigênio incluem em seu escopo, respectivamente, 12C, 13C e 14C e 16O e 18O. Exemplos de isótopos incluem 2H, 3H, 11C, 13C, 14C, 36Cl, 18F, 123I, 125I, 13N, 15N, 15O, 17O, 18O, 32P e 35S.[0041] The compounds described in this application may contain one or more isotopic substitutions, and a reference to a particular element includes within its scope all isotopes of the element. For example, a reference to hydrogen includes in its scope 1H, 2H (D), and 3H (T). Similarly, references to carbon and oxygen include in their scope, respectively, 12C, 13C and 14C and 16O and 18O. Examples of isotopes include 2H, 3H, 11C, 13C, 14C, 36Cl, 18F, 123I, 125I, 13N, 15N, 15O, 17O, 18O, 32P, and 35S.

[0042] De maneira análoga, uma referência a um grupo funcional particular também inclui em seu escopo as variações isotópicas, a menos que indicado em contrário pelo contexto. Por exemplo, uma referência a um grupo alquil tal como um grupo etil também cobre variações nas quais um ou mais dos átomos de hidrogênio no grupo está na forma de um isótopo de deutério ou trítio, por exemplo, como em um grupo etil no qual todos os cinco átomos de hidrogênio estão na forma isotópica deutério (um grupo perdeuteroetil).[0042] Similarly, a reference to a particular functional group also includes within its scope isotopic variations, unless otherwise indicated by the context. For example, a reference to an alkyl group such as an ethyl group also covers variations in which one or more of the hydrogen atoms in the group is in the form of an isotope of deuterium or tritium, for example, as in an ethyl group in which all the five hydrogen atoms are in the isotopic form deuterium (a perditeroethyl group).

[0043] Os isótopos podem ser radiotivos ou não radioativos. Em uma modalidade, os compostos não contêm isótopos radioativos. Tais compostos são preferidos para uso terapêutico. Em uma outra modalidade, no entanto, os compostos podem conter um ou mais radioisótopos. Compostos que contêm tais radioisótopos podem ser úteis no contexto de um diagnóstico.[0043] Isotopes can be radioactive or non-radioactive. In one embodiment, the compounds do not contain radioactive isotopes. Such compounds are preferred for therapeutic use. In another embodiment, however, the compounds may contain one or more radioisotopes. Compounds containing such radioisotopes may be useful in the context of a diagnosis.

[0044] Certos compostos de fórmula I marcados isotopicamente, por exemplo, aqueles que incorporam um isótopo radioativo, são úteis em estudos de distribuição tecidual de droga e/ou de substrato. Os isótopos radioativos, isto é, 3H e 14C são particularmente úteis para tanto tendo em vista sua facilidade de incorporação e meios de detecção rápidos. A substituição com isótopos mais pesados, isto é, 2H, pode oferecer certas vantagens terapêuticas resultantes de maior estabilidade metabólica, por exemplo, meia-vida in vivo aumentada ou necessidade de dosagem reduzida, e dessa forma pode ser preferida em algumas circunstâncias. A substituição com isótopos emissores de pósitron, tais como 11C, 18F, 15O e 13N, pode ser útil em estudos de tomografia por emissão de pósitron (PET) para examinar a ocupação do receptor. Os compostos de fórmula I isotopicamente marcados geralmente podem ser preparados por técnicas convencionais conhecidas pelos especialistas na técnica ou por processos análogos àqueles descritos nos exemplos e preparações que acompanham este relatório usando um reagente isotopicamente marcado apropriado no lugar do reagente não marcado anteriormente empregado.[0044] Certain isotopically labeled compounds of formula I, for example, those that incorporate a radioactive isotope, are useful in drug and/or substrate tissue distribution studies. Radioactive isotopes, that is, 3H and 14C, are particularly useful for this in view of their ease of incorporation and rapid means of detection. Substitution with heavier isotopes, i.e., 2H, may offer certain therapeutic advantages resulting from greater metabolic stability, e.g., increased in vivo half-life or reduced dosage requirements, and thus may be preferred in some circumstances. Substitution with positron-emitting isotopes such as 11C, 18F, 15O, and 13N may be useful in positron emission tomography (PET) studies to examine receptor occupancy. Isotopically labeled compounds of formula I generally can be prepared by conventional techniques known to those skilled in the art or by processes analogous to those described in the examples and preparations accompanying this report using an appropriate isotopically labeled reagent in place of the unlabeled reagent previously employed.

Solvatos podem ser preparados por recristalização dos compostos da invenção com um solvente ou mistura de solventes contendo o solvente de solvatação.

Preferred solvates are solvates formed by incorporating into the solid state structure (e.g. crystalline structure) of the compounds of the invention molecules of a non-toxic pharmaceutically acceptable solvent (hereinafter referred to as solvation solvent). Examples of such solvents include water, alcohols (such as ethanol, isopropanol and butanol) and dimethyl sulfoxide. Solvates can be prepared by recrystallizing the compounds of the invention with a solvent or mixture of solvents containing the solvating solvent. Whether a solvate has formed in any of the given cases can be determined by subjecting crystals of the compound to analysis using well-known and traditional techniques such as thermogravimetric analysis (TGE), differential scanning calorimetry (DSC) and X-ray crystallography. .

[0049] Os solvatos podem ser solvatos estequiométricos ou não estequiométricos. Solvatos particulares podem ser hidratos, e exemplos de hidratos incluem hemi-hidratos, mono-hidratos e di-hidratos.
